The PCI DT bindings contain a bogus entry for IO space which is not supported on Keystone. The current bogus entry has an invalid size and throws following error during boot.
[0.420713] keystone-pcie 21021000.pcie: error -22: failed to map resource [io 0x0000-0x400000003fff] So remove it from the dts. While at it also add a bus-range value that eliminates following log at boot up.
